It will be very difficult to silage alone , without taking wilt or lower water treatment( Giffel et . al . ,２００２ ) . This study was conducted to investigate whether mixing alfalfa with other forages and the use of anadditive( cai he) product could be used to enhance the quality of alfalfa silage .cai he is a kind of additive . Cai he belongs to theproduction of Shangdong Tianda CAihe Animal Health Co .Ltd .Materials and methods First‐cutting alfalfa and perennial lespedeza ( Lespedeza hedysaroides ) and ceratoides ( Ceratoidesarborescens ) were at full bloom period ,Hordeum ( Hordeum brevisubulatum ) was cut in the fruit phase . All forages were wiltedfor approximately ２d . Forages were chopped to a theoretical length of ２‐３ cm ,and alfalfa mixed with three other forages at ratioof １ :１ giving the four silage types listed in Figures . Additive was mixed in distilled water according to the manufacturer摧sinstructions (２５０g / tonne) and sprayed on to some of the forages providing the following treatments : １ ) control silage withoutadditive ( untreated) , ２ ) silage treated with additive( cai he) . Silage was then stored in ２０L plastic barrel and compacted , andsealed with double polyethylene plastic film . Each treatment was repeated three times .Results The additive ( cai he) significantly decreased the CF ( Crude Fiber) content and PH value of silage ( Figure １ ,２ ) .The CFcontent of single alfalfa silage(２３ .７１ ％ ) was significant lower than mixed silage without additive ,the CF content of alfalfa andlespedeza(２３ .５０ ％ ) was the lowest in all of the mixed silage with additive . The reduction of CF content indicated that the insideof silage happened strong microorganism fermentation .pH was the significant indicator of fermentation effect .The PH ofuntreated silage did not differ among silage types ( Figure ２ ) , however , PH of silage treated with cai he declined rapidly ,PH oftreated silage were lower than that of the untreated silage . The PH value of alfalfa and hordeum silage was significantly lowerthan other mixed silage types .Figure 1 CF variation o f mixed silage .Figure 2 p H variation o f mixed silage .Note : Type １ : Al f al f a ; Type ２ : Al f al f a and Lespedeza(１ :１ ) ; Type ３ : Al f al f a and Ceratoides(１ :１ ) ; Type ４ : Al f al f a and Hordeum (１ :１ )Conclusion Additive can improve the fermentation quality of mixed silage and reduce the CF and PH value of silage . Alfalfa andLespedeza (１ :１ ) was effective according to the routine nutrition ingredients .Referenceste Giffel M C , Wagendorp A , Herrewegh A ,Driehus F . ２００２ .
